Thank you for replying, Carl. I have compiled git head (ffmpeg
N-102655-g282b9f4cba) and the issue persists, log appended.

I have uploaded a working [1] and non-working example [2]. I can
provide additional files or share via another method if desired.

1: https://roberthallam.com/IMAG0085.AVI
2: https://roberthallam.com/IMAG0065.AVI

Thank you for your time. If there is anything else I should include,
please let me know.

Cheers,
Rob
